摘　　要：文章阐述了构造地球化学找矿研究的一些基本问题:构造地球化学找矿的发展历程、方法依据、不同类型含矿构造的地球化学特征、构造地球化学找矿的研究内容和工作程序、工作方法和方法特点。以云南富宁县那能金矿区为例,运用构造地球化学方法对微细浸染型金矿进行了找矿研究,厘定了矿区控矿构造为一右列雁行褶皱带,确定了成矿元素组合为Au、As、Ag、Mo,圈定了两个金异常带,并证实为金矿体所致。A few basic questions are discussed on the Tectono-geochemieal mineral prospecting method, including its history, theory basis, study con-tent, working process, working methods and characters. The geochemical characters of different types of ore-controlling structures are summarized. The Naneng gold mine in Funing County, Yunnan Province was studied as a case. The deposit is a sediment-hosted, disseminated gold deposit with multi-element anomaly of .Au, As, Ag and Mo, two geochemical anomalous zones were identified which were proved to be resulted from gold orebodies and controlled by en echelon fold.
